WELL BARREL.

Application led August 31, 1927. Serial No. 216,671.

This invention relates to working barrels for oil wells.

It is a well known fact that where conditions are normal, that thel 2 by 6 working barrel havingV either canvas or leather cups constitutes the best means for pumping oil from the earth; but where sand and gas pressure are encountered, the use of this barrel has proven too expensivebecause of l0 the pulling operations necessitated;

It is to overcome this objection that thisinvention is designed and a primary object thereof is to so construct such a barrel that it will operate as a gas trap permitting the fluid to run in and prevent the gas from working on the valves, thereby effecting a great saving to the producer.

Another object. is to construct the barrel so that if sand enters with the vfiuid `the greater portion of it will be trapped and thus prevented from sticking any of the valves.

In carrying out these objects the invention is susceptible of a wide range of modi- V ications without departing from the spirit or sacrificing any of the advantages of the claimed invention; there being shown in the drawings for illustrative purposes a preferred and practical form, in which Figure 1 is a longitudinal section with parts in elevation of a well barrel constructed in accordance with this invention.

Figure 2 is an enlarged detail section of the upper end of the barrel indicated by A*the line 2 in Fig. 1,

Figures 3 and 4 are similar views showing successive portions of the barrel and indicated by the lines 3 and '4,of Fig. 1

Figure 5 is a similar view of the next sucvceeding portion of the barrel with a portion of the working valve in section, this figure being indicated by the line 5 of Fig. 1,

Figure 6 is a vertical section of a continuation of the portion shown in Fig. 5, show- `Y ing the remainder of theworking barrel and the improved standing valve connected therewith, together with the bottom of the barrel which is to be connected with the well tubing and indicated by the line 6 in Fig. 1,

taken respectively on the lines 9 9 andk 10 10 of Fig. 6. y

This working barrel is designed to be connected at its upper end with the well tubing shown at T in Fig. 1., and at its lower end with anchoring tubes, not shown, and is composed of a tubular connection 1` internally threaded at its upper end for connection with the tubing T and exteriorly threaded atits lower end for connection with a tubular steel outer shell section 10 which latter is detachably united by a coupling 20 in the form of a steel sleeve or collar, with a steel pipe or outer shell section 30. These sections 10 and 30 are preferably of the same shape and size as shown inFig. 1,

- said collar 2O being also of the same size.

The connector 1 has a rope socket neck 2 at its upper end and its lower end is enlarged and oi'set outwardly, as shown at 3, the inner face of said enlargement being beveled or inclined outwardly as shown at 4, to provide space to receive the upper end of a valve protecting casing 15 in which is housed the upper portion of the valve stem 5. This valve stem 5 extends above the reduced neck 16 of the casing 15'and is provided with an enlargement or head 6 having a shoulder 7 at its lower end which is designed to rest on the upper edge of the neck 16 to seat stem 5, it being understood that when the pump is in operation the stem 5 works up and down in the casing 15. The stem 5 is threaded at its upper terminal as shown at S, for connection with the well rods, not shown. The stem 5 also has an enlargement or head 5a near its lower end for a purpose presently to be described. f

The casing 15 extends through and is held in position within the shell 10 by a guide member 11 provided with a plurality of apertures 12 for a purpose hereafter to be described. This casing 15 is provided at its upperend below said guide 11 with a` plurality of openings 17, twenty ot which are preferably used, and `which permit the outfiow ot the oil therefrom, as will be presently described. The casing 15 has its lower end tapered as shown at 18 and designed to fit tightly within a correspondingly shaped socket 24 formed in the upper endv of the collar 20 and which is held in said col lar by friction. The casing 10 has threaded connection with the upper end of the col- Vlar or coupling 20 as shown clearly in Fig.

e thereof. From this chamber the oil passes up through the valves 52 and 53 into chamber 58 and through the openings 59 to the center of valve 50 passing upwardly through the bore 59a thereof into the working valve 60 from whence it passes to the cast iron barrel 25 and up through the casing 15 and out of the apertures 17 thereof into the casing 10 from whence it passes through the openings 12 in the guide 11 up through the member l and out of the tubes, not shown.

In this passage of the oil any sand which may enter with it through the openings 31 into the casing 30 drops down through the central opening 59a in the valve 50 and passes through the member 40 into the anchoring tubes connected therewith and which are closed so as to form traps for the sand. The sand remains in these traps until the barrel Vis drawn out for cleaning.

The oil in itsrflow upwardly through the working valve when passing out into the casing l will be separated from any sand which may be carried thereby, the sand dropping down through the vcasing to the bottom thereof, as yshown in Fig. 3, while the oil passes out in the manner above described.

Vhen the casing l5 is raised by the pulling of the rods it will be unseated from the coupling by reason of the engagement with its lower end by the head 5 of said stem thereby allowing the sand which has settled in the bottom of the casing 10 to drop down through the valve 50 and member 40 to the anchoring traps below.

In assembling the sections when the barrel is screwed into the top ol the standing valve 5() the collar 20 is simultaneously screwed into casing which is possible owing to the fact that the threads are the same on these members.

lVithout further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course, be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the lspirit of the invention or its scope as claimed.

I claim 1. A working barrel for oil wells comprising an outer casing composed of longiy tudinally alined sections, a coupling detachably connecting said sections, a tubular valve proteetorlocated in the upper casing section and spaced therefrom with its lower end frictionally held in said coupling forming a sand collecting chamber between it and the jasing, its upper end havinfr oil outlet apertures, a working barrel in the other casing section connected with said coupling, a standing valve connected with the other end of said barrel and said casing section, a valve stem extending through said protector and connected with said barrel and having means to engage said protector and unseat it on the raising of the stem, a connector detachably connected with the upper end of said outer casing, a working valve connected with said stem, and means located at spaced intervals onsaid working valve to prevent the passage of sand whereby the working members of the valve are protected.

2. A working barrel for oil wells comprising sectional inner and outer casings radially spaced from each other and connected to form a sand collecting chamber between them, the inner `casing having an oil outlet at its upper end and the outer casing having an oil inlet below the sand chamber, a Valve stem extending through said inner casing, a working valve connected with said stem, and a standing valve connected with said working valve and provided with means for separating the sand trom the oil.

3. A working barrel for oil wells including a standing valve comprising a body member having means for connection withV a barrel casing and a working valve, oil chainbers at the top and bottom of said standing valve with passages extending through the body and discharging into the bottom chamber, valved passages between the two chambers, and a bore extending through said body and connected with said top chamber.

1. A working barrel for oil wells including a connector having means ior connection with the well tubing, an outer casing depending rom said connector and having an apertured guide member and a coupling located therein, a tubular valve protector or inner casing extending through and centered by said guide and seated in said coupling, said protector having oil outlet openings at its upper end below said guide, a valve stem extending through said protector and having an enlargement to engage and unseat said protectorI when the stem is lifted to discharge the sand collected between said protector and outer casing above said valve.
